摘要
介绍了音频大地电磁测深和激电测深两种物探方法在新疆鄯善县某铁矿勘查的应用研究。在矿区地质概矿简述中分别介绍了矿区地层、地质构造和岩浆岩情况,并通过对本矿区地质、地球物理特征分析来选择综合物探方法,并以大地电磁测深、磁法测量成果为主、激电测量次之的原则进行解译,圈定出了异常带,推测出并提供钻孔位置,也验证了此音频大地电磁法和激电磁法相结合的综合物探方法的有效性,在寻找磁铁矿及其空间定位方面效果显著。
This paper introduces the application of audio--frequency magnetotelluric and IP sounding methods to an iron ore in Shanshan county of Xinjiang. The paper describes layers in ore district, geological structure and magmatic conditions in the resume of ore district ge- ology summary, and chooses integrated geophysical methods for the mine through the geo logical and geophysical characteristic. The interprets based on magnetotelluric sounding a chievement and magnetic survey achievement, with the help of IP measurement, not only delineates the anomaly, speculates and provides drilling position, but also verifies the effect of integrate geophysical methods of audio frequency magnetotelluric sounding and IP sound- orientation.
